    Programming the Unit - Card Handle 1 The 65-223 can be programmed as “Card Handle 1” where it is divided into 1 sub-unit for the matrix and 1 sub-unit for the isolation switches. This is summarised in Table 4-1 below and Figures 4-1, 4-2 and 4-3.
  • Page 35 Programming the Unit - Card Handle 2-7 The 65-223 can alternatively be programmed as a separate “Card Handle” for each plugin module where each is divided into separate sub-units - one for each matrix and two for the isolation switches. This is summarised in Table 4-2 below.
